Two worlds that should have never met collide violently as a dimension hopping Pokemon is released from its bindings by greedy, short sighted thieves. The young Sword of Justice-in-training (Y/N), her partner Keldeo, and scout Corvisquire are flung into the land of Fodlan along with an unknown amount of Pokémon. Taken in by the mercenaries Jeralt Eisner and his daughter Byleth, (Y/N) and Keldeo must offer their knowledge and services to the Church of Seiros at it's suspicious archbishop along with playing students under the Blue Lion House. With no clear path home and with Pokémon appearing all over Fodlan, the pair must uphold the duties of a Sword of Justice, but as their friendships deepen with the residences of Garreg Mach Monastery, they find themselves tangled in church corruption, politics, and all out war, and they soon learn that this world, like all others, is far from black and white.
